But there’s some work to be done before the stars are officially back on. “Gaga told Taylor that she knows that she has trust issues,” the source says, “and she admits she needs to give him his space.”

Shortly after the breakup, an insider told Life & Style that, “Gaga would constantly call Taylor on the set of Chicago Fire, and even made friends with crew members so she could basically spy on him. He got fed up.”

So the "Perfect Illusion" singer is working to leave that sort of behavior in the past. “She told Taylor that she’s making sure she’s 100 percent ready to be in a mature, loving relationship without the jealousy and control issues,” the source says.
